DEEP-SEA FISHES (di-awn to various scales) 



The fishes of the deep sea are highly carnivorous forms, often 

 provided with formidable teeth. The eyes are either very large oi- 

 else greatly reduced. Luminous organs are often present. Many ot 

 these fishes are of bizarre appearance, as may be gathered from 

 the plate, which represents eight species, as follows : — 



1. Sternoptyx diaphana: small and translucent, with rounded 



luminous organs on the sides of head, body, and tail. 



2. Cyema atruin : a small deep-sea eel, with reduced eyes. 



3. Malacosteus Indicus: very large eyes, two luminous organs 



on the side of the head, and enormous mouth. 



4. Idiacanthus ferox : a greatly attenuated form, with numer- 



ous small rounded luminous organs on the side of the 

 body. 



5. NemichtJiys ingens : a greatly elongated deep-sea eel, with 



large eyes, and jaws drawn out into a slender beak. 



6. Saccopharynx ampidlaceics : a large deep-sea conger-eel, 



which has succeeded in swallowing a fish much bigger 

 than itself. 



7. Baihypterois longicaiida : a deep-sea fish with reduced eyes, 



and much elongated fin-rays serving as feelers. 



8. Macrurics crassiceps : a species of a widely distributed deep- 



sea family related to that including the cod, &c. Eyes 

 extremely large, and mouth on the under side of the head.
